JOHN FLEMING, OF TORONTO, ONTARIO, CANADA.

MACHINE FOR CASTING PRINTERS LEADS.

SPECIFICATION formingpart of Letters Patent No. 233,608, dated October26, 1880.

Application filed May 12, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN FLEMING, of the cityof Toronto, in the county of York, in the Province of Ontario, Canada,manufacturer, have invented certain new and useful Improvements inMachines for Oastin g Leads for Printers Use, of which the following isan exact description.

My invention relates to machines for easting printers leads; and itconsists in certain improvements therein, hereinafter more fully setforth.

Referring to the accompanying drawings, Figures 1 and 2 arecross-sections of a machine for casting leads in the construction ofwhich my improvements are embodied. Fig. 3is a plan, and Fig. at an end,view of the same. Fig.5 is a perspective in detail of the lead-gate.

The apparatus consists of a flask, A, made in two sections, A and Awhich are coupled together at their-lower ends by a slotted hingejoint,a. p

The base-plate A of the flask is provided with a clam ping device, B, bywhich the plates are clamped together when the lead-gate O is placedbetween for casting, and in order that the plates of the flask may beseparated to permit of the removal of the lead-gate the beam B of theclamp is made adjustable and is provided with a screw, B

The flask is provided with central journals, b, mounted injournal-bearings d 61 upon a frame, D, in such manner that the flask canbe turned to and supported in either of the positions shown in Figs. 1and 2.

The 1ead-gate O is provided with a series of parallel longitudinalopenings, 0, which correspond in width with the lead in the rough, andcare is taken to make the gate of a uniform thickness throughout itssurface.

The inner faces of the flask-sections are covered with a layer ofasbestus, paper, or other material, which will prevent the meltedmaterial of the leads cooling before it reaches the bottom of theopenings 0.

In operation the lead-gate is inserted between the sections of theflask, and the flask clamped up and placed in the position shown inFig. 1. The melted composition of which 0 the gate in a most perfectmanner. So soon as 5 5 the metal is cool enough the flask is tilted inthe position shown in Fig. 2, and the gate removed by unfastening theclamp.

After the leads and slugs are thus cast in parallel bars ofapproximately the proper width and thickness, they are placed in aplaning-machine and finished and cut up in the ordinary way to thestandard sizes required.

The advantages of my invention are rapidity and economy in theproduction of leads and slugs by the saving of labor and time.

I claim as new and desire to secure by Letters Patent- The combination,with the swinging flask A, provided with central journals, 1), andcomposed of the two sections A A coupled to gether by the slotted hingedjoint a, of the frame D, having journal-bearin gs d d, clamping deviceB, attachedto the lower section, A and provided with the beam B B andleadgate 0, having a series of longitudinal openings, 0, substantiallyas described, and for the purpose set forth.
